She should bring 48 ounces bc she has 16 scouts and each of them need 2 cups so: 2x16=32 so that means there are 32 cups in total and now you need 3 tbs per cup so: 3x32=96 so that means you will need 96 tbs of mix in total now you transfer units from tbs to ounces and since half an ounce is one tbs you divide by two: 96➗2=48

that's how I read it.... to get some value between 1 and 5, namely 4, to make the expression a rational, well, 48 can be expressed as 48/1.
